Systematic, scientific and effective alarm system is vital for improving production process safety, quality and operability performance. It has attracted wide attention of industry and academics, and achieved numerous research results. The latest research progress in the process alarm systems are summarized respectively from alarm system optimized design, alarln system monitoring and alarm system performance assessment these three hot research directions, with discussion and comparison on different methods. As to alarm system optimized design, ROC analysis, correlation analysis and some other methods are used to optimize alarm thresholds, and alarm prioritization is also included. In view of alarm system monitoring, nuisance alarms are identified by correlation analysis, meanwhile causal alarms are identified by process knowledge and data-driven means, and chattering alarms are processed by time window or run length distribution. Concerning alarm system performance assessment, qualitative and quantitative assessment is executed based on standard and codes of process alarm management or dynamic risk analysis. Finally, some valuable research directions and trends regarding alarm systems are pointed out, and the relevant research perspectives are highlighted for future.
